Patent CA-2213423-A1 (CA)
Title: Method for shared memory management in network nodes
Inventor: MITRA DEBASIS
IPC: H04L12/56
Filed: 1997-08-18
Abstract: The invention concerns a method for a multi-port node having a shared buffer memory to provide enhanced data packet buffering capacity for established virtual circuits (VC's) through the node and one of its output ports while maintaining grades of service commitments. The method admits incoming data packets to a node for an established VC based on a determination of combination of factors including the effective memory requirements for each output port as VC's are created or terminated, the portions of buffer memory in use for conveying packets through the intended output port for the incoming packet, and the total amount of available shared memory in the node. Such determinations enable the node to better decide whether admitting the incoming packet would cause a disproportionate allocation of the shared memory for the intended output port. As a consequence, a relatively high packet buffering capacity can be achieved substantially without violating grades of service commitments.

Title: A method and apparatus for delivering data from an information provider using the public switched network
Inventor: KOWAL JAMES ALLEN
IPC: H04M3/42
Filed: 1997-10-06
Abstract: The customer performs a search or otherwise defines selected data maintained by the information provider. Once the selected data is identified, the information provider maintains the requested data, typically by maintaining pointers identifying the data, but delays delivery of the requested data until the scheduled delivery time, such as a particular day and time requested by the customer or a non-peak period as determined by the information provider. When the information provider determines that delivery is appropriate, it makes a request for a suppressed ringing connection to a switching system. The switching system responds to the request for connection by creating a suppressed ringing connection where a silent alert tone or digital alert signal is transmitted to the customer premise equipment. The customer premise equipment includes a receiving system that receives one or more tones from the switching system over the suppressed ringing connection and becomes active. Upon being activated, the receiving system causes the customer'scomputer or portions of the computer such as a particular memory to power-up such that the computer can receive the data from the information provider.
